Just enter your birthday to get your free daily biorhythms, shown in a biochart. Test your physical shape and fitness.

Quick overview:

When the curve is above the midline, we experience a "high" in the corresponding field (physical, emotional or mental).
When the curve of any cycle is below the midline, we experience a "low" in the corresponding field.
When any of the curves crosses the midline, this is a critical time in the corresponding field.
